block: make part_in_flight() take an array of two ints
Instead of returning the count that matches the partition, pass in an array of two ints. Index 0 will be filled with the inflight count for the partition in question, and index 1 will filled with the root inflight count, if the partition passed in is not the root. This is in preparation for being able to calculate both in one go.
